.SH DESCRIPTION
The \fBpriv_getbyname()\fR function maps a privilege name to a privilege number
for use with the \fBpriv_*()\fR kernel interfaces.
.sp
.LP
If \fBPRIV_ALLOC\fR is passed as a flag parameter, an attempt is made to
allocate a privilege if it is not yet defined. The newly allocated privilege
number is returned.
.sp
.LP
Privilege names can be specified with an optional \fBpriv_\fR prefix, which is
stripped.
.sp
.LP
Privilege names are case insensitive but allocated privileges preserve case.
.sp
.LP
Allocated privileges can be at most \fB{PRIVNAME_MAX}\fR characters long and
can contain only alphanumeric characters and the underscore character.
.SH RETURN VALUES
This function returns the privilege number, which is greater than or equal to
0, if it succeeds. It returns a negative error number if an error occurs.
